This research aims to analyze the measurement, monitoring, and estimation of biomass and
carbon using allometric equations and remote sensing estimation. The study will be conducted
with data collected at Fazenda Piave, located in the municipality of Igarapé-Açu. The property,
which spans 75 hectares, is dedicated the agricultural and forestry production, being mostly
composed of secondary forest. The research intends verify the estimates obtained by both
methods, seeking identify statistically significant differences. Initially, the biomass and carbon
quantities in the area will be analyzed using allometric equations with data collected in the field

and subsequently for remote sensing, the estimative will be conducted using scenes of Sentinel-
2 satellite on the Google Earth Engine platform in the Python programming language, with

applying distinct spectral indices, NDVI, EVI, SAVI and NPP. The study objective is achieving
the best biomass and carbon estimation using the allometric equations and spectral indices,
evaluating the differences between the estimates in terms of precision, accuracy, bias, temporal
monitoring and cost.
